heteroseparatist: a : A person, entity, or organization that respectfully declines to associate with any or all divisions of the gay, lesbian, bisexual, or transgender community, but does not hate, fear, or persecute people that are GLBT. b : A person who quietly shuns people and environments that are antihetero.

When I was called a homophobe, I explained what a heteroseparatist was.

Someone who seeks to mask their discriminatory words and actions with regard to homosexuality beneath a veil of high minded moral disapproval. Someone who believes heterosexual couples are superior to homosexual couples, and therefore deserve respect and rights that are not afforded to heterosexuals.

Person 1: Can you believe that guy? What a homophobe!
Person 2: No, no! He's a 'heteroseparatist'.
Person 1: Oh, so he's like a homophobe, but with less integrity and honesty?
Person 2: Yep.
